Recently I have been having problems with a RPZ(W) and connections.
Originally it was working nicely. Then one day it started dropping off line for no reason.
Being headless, it was difficult to know what was happening. Alas a power cycle was the only way to get it up again.
Then one day I looked at the logs as I noticed it going AWOL / offline.
It was not much I could understand, but I carried on investigating.
What has thrown a spanner in the works is today/this morning.
Last night the RPZ was up and working.
All the machines use
MQTT to talk to one another and if/when they are disconnected, they send a message.
That's all well and good.
So: Last night it was online, working.
I powered down this machine, not it, not the
This morning, I got up and looked at the
Green one is the
MQTT host and the grey one is the RPZ.
Now, ok, I'm confused too.
Green one: 06:25:52 TelePi comms up. (RPZ)
That is about when I turned on this machine. I saw the LED blink as I turned it on. (Or I think I did.)
Grey one: 06:26:49 TelePi comms up.
That's nearly 1 minute later.
Why did I get that message? (Semi-rhetorical) If it (TelePi) was already up why would it send that message again?
Alas the LOG file isn't turned on, so I can't look at the actual log. Drats.
But I'm curious to what is going on here and why.
The two machines are 2 m apart. It isn't like they are in different rooms with walls between then.
Thanks in advance.
